Red light therapy claims to heal wounds, improve pain and reduce wrinkles. But the evidence for it working is dim
Without strong evidence, or at least one decent trial, we cannot know whether shining red lights on to your skin does anything
TL;DR
- Red light therapy is a popular wellness trend with claims of healing wounds, reducing pain, and improving skin conditions like acne and wrinkles.
- Despite widespread claims, the scientific evidence supporting red light therapy is weak and unclear.
- Most studies are small, poorly controlled, and suffer from methodological issues, making it difficult to draw reliable conclusions.
- Lack of standardization in wavelengths, intensity, and session length further complicates research.
- It is challenging to conduct blinded studies for red light therapy, and subjective measurements can introduce bias.
- While some limited data exists, it is not considered strong evidence, and significant benefits are unlikely.
- The potential benefits might be comparable to simple lifestyle changes like a short walk outside.
